The design is useful and marketable to people with diverse abilities.
Design Goals:
• Avoid segregation or stigmatization of any users.
• Provide the same means of use for all users — identical whenever possible; equivalent when not.
• Ensure privacy, security, and safety are equally available to all users.
Detailed Explanation
Equitable Use is about ensuring that designs cater to everyone, regardless of their abilities. The goals here emphasize eliminating any separation that might occur due to differing abilities. For example, achieving identical access means creating a space where everyone can enter without special treatment. Providing equivalent means of use refers to ensuring that if an identical means isn't possible, a suitable alternative is presented, ensuring that nobody is left out. In addition, everyone's privacy, security, and safety should be considered, allowing for a space where all users feel protected and secure.
Examples & Analogies
Imagine a public building with a single entrance that has an automatic door. This allows people using wheelchairs as well as those who walk to enter without anyone needing to assist them. This not only enhances the experience for all but also avoids any feelings of segregation or dependency among users.
